1. Science presentation on organisms… We’re all going to the zoo!!!

2. Question 1. Habitat… Habitat: The natural home or environment of an animal, plant, or other organism.

3. Question 2. Describe and explain what we mean by ‘adaptation’… Organisms are adapted to survive in different conditions. Over many generations, these adaptations have come about through variation. Variation involves small changes between organisms which may allow that organism to compete better for survival. Variation can have environmental or genetic causes. Adaptation Darwin's theory of evolution explains how species of living things have changed over geological time. The theory is supported by evidence from fossils and by the rapid changes that can be seen to occur in microorganisms such as antibiotic-resistant bacteria. Many species have become extinct in the past, and the extinction of species continues to happen.

4. Question 3. Describe and explain how some organisms are adapted to live in their habitat… Every organism has certain features or characteristics that allow it to live successfully in its habitat. These features are called adaptations, and we say that the organism is adapted to its habitat. Organisms living in different habitats need different adaptations.

5. The polar bear Polar bears are well adapted for survival in the Arctic. They have: a white appearance, as camouflage on the snow and ice thick layers of fat and fur, for insulation against the cold a small surface area to volume ratio, to minimise heat loss a greasy coat, which sheds water after swimming.

6. Arctic plants The Arctic is cold and windy with very little rainfall. Plants in the Arctic often grow very close to the ground and have small leaves. This helps to conserve water and to avoid damage by the wind. Extreme environments: Some organisms are adapted to extreme environments: for example, deep sea hydrothermal vents. Pompeii worm: The Pompeii worm is adapted to the high temperatures and pressures of the hydrothermal vents by: using a thick layer of bacteria to protect it from heat hiding inside a papery tube to protect it from predators. In an exam you will need to be able to describe the variation and explain how it helps the organism to survive.

7. Question 4. Describe and explain conservation… Official supervision of rivers, forests, and other natural resources in order to preserve and protect them through prudent management. A district, river, forest, etc., under such supervision.
